Key Ingredients

- Sage: Choose vibrant, silvery-green leaves for the most pronounced flavor
- Heavy Cream: Essential for achieving the richest texture and preventing separation
- Gruyère: Aged varieties with crystallization provide optimal nutty depth
- Walnuts: Fresh nuts with light coloring ensure the best flavor once toasted

Recipe Variations
The basic recipe adapts well to dietary modifications. Coconut cream offers a dairy-free alternative while maintaining richness. Nut-based cheese substitutes work effectively, particularly cashew or almond varieties. Consider adding wild mushroom layers or hemp seeds for texture variation.

Store cooled gratin in airtight containers. Flavors develop beautifully overnight, making this ideal for advance preparation. Before reheating, bring to room temperature and add a touch of warm cream to restore the original texture.
This gratin exemplifies how careful technique elevates simple ingredients. The methodical preparation yields a dish that demonstrates both refined cooking skills and nurturing comfort, perfect for gathering people together.
Frequently Asked Questions
